Volkswagen Tiguan check engine light comes on

Filed Oct 20, 2026 · Electrical, Engine · OH

Engine light on at around 50K - dealership said it was just an "issue with the warning lights" don't worry unless it blinks. At 74K I found out the turbo boost was the reason for this and I should have been told when the car was still under warranty. Realized in December of 2020 the car was soaking wet inside. Front and Back carpet was soaked like a sponge. Thought it was from driving in slush - turns out it's the moonroof drains. Repaired by VW dealership - all carpet and padding was ripped out and had to dry and then be reinstalled. Dealership ripped the interior moonroof headline while installing and didn't tell me. Huge fight with insurance - finally got fixed. Was told Cam cover leaking, and needed manifolds cleaned because of direct injection engine. Car has no power anymore. Car towed multiple times for jerking and flashing engine light. 2 engine coils replaced within 6 months. Even with moonroof drains cleaned yearly - car still gets wet inside and visible moisture on dashboard. Both back coil springs broke Aug 2026. Didn't realize until I saw the 2nd one laying in the driveway. $800 to repair those. Known recall issue with 2015 coil springs breaking by VW. But did include 2013 models. Dangerous to drive not knowing they have broken. No light indicator. Engine light always on because of Turbo boost. Now constantly needing coolant. Washer fluid, tire air pressure lights & gas cap light always on even when full of fluid. Broken tether to gas cap. Not even 90K miles and this car is constantly being towed to the shop. ABS brakes slightly jumpy at very low speed. Knocking sound in engine. Constant fear when driving this vehicle

While driving a 2026 Volkswagen Tiguan in Los Angeles County, CA, the vehicle spontaneously and without driver input shifted itself into Neutral. The vehicle experienced a complete loss of motive power and stopped driving. I was travelling with my newborn infant in the back seat when the vehicle lost propulsion in active traffic, creating an extreme and immediate collision hazard. The vehicle had to be coasted to the shoulder under hazardous conditions. Car literally stopped in the middle of a busy intersection. Several dashboard lights came on during this incident. The next day the engine light turned on.

The engine cuts off WHILE DRIVING and hard stops the car. OBVIOUS safety issue for myself and 3 children. The car is still “on”, the car is still in DRIVE but nothing happens when I press the gas, it feels like the E brake is engaged, I get the on and off pop up text - no check engine or any other warning or text - that says “please start engine manually”. When I press the ignition button the car cuts completely off. I then have to press it again to fully start the car again. Hard stopping at any MPH in traffic or intersections, etc. could be deadly. I’m a single mom of 3 with no other transportation. Local VW told me the diagnostic was fine. They’ve tried blaming it on seatbelt safety mechanisms - that is NOT what’s stopping the car. We all buckle and stay that way, it’s GA law. Even if it did this over a seatbelt I’d be concerned as to how a car hard stopping at any mph in the middle of traffic is any safer than unlatching a belt! The dealership is fully aware. VW corporate is fully aware. Case #07796308. No accidents at all. No outside maintenance. No inspections by anyone other than the one at the dealership mid Sept. This is becoming more frequent. This was a known issue in 2025s and there is an open recall for 2026s, per my research, but for some reason my VIN isn’t coming up in it.

I am writing because of a premature rear axle coil spring fracture , which could have caused immediate risk of tire puncture and loss of vehicle control. An engine light had come on in our vehicle, and we brought it in to the dealer to find out why. They could not find any reason that the light had come on, and said everything was fine, but that they did find that the rear spring was broken. We are aware that in 2019, Volkswagon had a recall on some of its models, and I believe that there is a design flaw that made this happen in our vehicle. The technician sent us a video of the situation. Unfortunately, the file of this video is too large to attach.

This is an additional complaint concerning the same vehicle previously reported under ODI XXX. On XXX, while the vehicle was in Drive and moving at approximately 5 mph in [XXX], it unexpectedly shut off and shifted itself into Park. On XXX, while reversing, the vehicle suddenly lost all power and the engine shut off while the transmission was still in Reverse. The vehicle had to be shifted into Park before it would restart. Photographs were taken immediately after the XXX incident and are available. These repeated shutdowns created a serious risk of a crash or injury. The vehicle has an extensive repair history, including a transmission replacement, but continues to experience hard shifting, vibration at all speeds including during acceleration, intermittent check-engine lights, electrical problems, camera and infotainment failures, and remote-start failures. There was no immediate warning before either shutdown. Volkswagen has been notified. The vehicle is now included in Volkswagen safety recall 57KL/the federal safety agency 26V587 for Body Control Module software that may reset unexpectedly, switch off the ignition, cause an engine stall, and disable controls, warning lights, exterior lighting, or the rearview camera. The recall remains incomplete. The vehicle is available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have only ever serviced this vehicle at VW dealerships, and took the car in for service every 10k miles. The check engine light came on just under 50k miles and it was due to a cracked Leak Detection Pump. I paid for the repair out of pocket. After it was fixed, just a few weeks later the check engine light came back on. When I took the car back to the same dealership, they diagnosed the problem as a cylinder head issue requiring cylinder head replacement and quoted a significant cost to fix. It is not covered under warranty even though I am just barely over the 50k mile mark. There is a common and known, recurring issue with the engine on the 2022 VW Tiguans and it is a shame that there is no recall already issued for this.

We have to add 1-2 quarts of oil every 600 miles. Our check engine light came on 02/2026 for carbon buildup. We had it cleaned, had timing chain replaced, piston rings, oil valves, manifold. Cost us $5300. The car ran fine before the light came on and all of a sudden it started making grinding noises and idling rough. We change the oil every 3,000 miles and the car burns through oil constantly. Our car stalled 4 times on the highway since then almost causing wrecks, it runs rough and now our check engine light is back on for the same issue. It’s causing emotional and financial distress. There are multiple lawsuits pending for this but something needs done. This is exhausting.

Symptoms started at 65k-70k miles, just after 50k warranty expired. First symptom was low oil warning and needing to add oil between changes. Then oil spots, then i found a bad leak and replaced oil pan, timing chain cover and assembly, turbo actuator. Warnings progressed to frequent low oil light, check engine light, blue smoke on start and acceleration, strong burning oil smell, and now visible oil spitting from tailpipe onto rear windshield. I now have to carry oil every time I drive. Timeline: bought new with 5 miles, no issues to 65k, 65k-70k start of leaks, 84k now 2 quarts per 50 miles and oil from exhaust. Ive notified VW about the situation.

2023 Volkswagen Tiguan, approximately 34,316 miles. While driving on I-26 in South Carolina, the EPC warning and amber warning triangle illuminated. I pulled over and stopped. After approximately 10 minutes, I restarted because I was in an unsafe location. No warnings were displayed after restarting, but approximately five miles later they returned, and I exited the highway. After stopping, extensive engine oil was visible on the rear/underside of the vehicle. I immediately checked the dipstick and no oil was visible. At no time did I observe a low-oil-level or low-oil-pressure warning. An authorized Volkswagen dealer diagnosed a faulty oil separator causing internal engine pressure to build, which caused the oil pan to crack and upper timing cover to leak. The oil separator, oil pan and upper timing cover were replaced under warranty. During approximately two months before the failure, the vehicle had several times briefly displayed “Max engine speed: 3,000 rpm.” The night before the incident, the check-engine light illuminated but was no longer illuminated before the return trip began. The vehicle had received scheduled service, including an oil/filter change, at approximately 29,780 miles, only about 4,500 miles before this failure. My safety concern is the sudden pressure-related engine failure and major oil loss at highway speed, together with no observed oil warning despite no oil being visible on the dipstick immediately after the incident. The servicing dealer has stated that it does not know what causes these oil separators to fail. I am reporting this incident so the federal safety agency can evaluate whether it may represent a broader safety issue.

On 8/29/2026, my 2024 Volkswagen Tiguan experienced a sudden mechanical failure while I was driving on the highway at approximately 55mph, with only 27,842 miles. Prior to this incident, I had reported to the VW dealership at my previous oil change that I repeatedly had to add oil between scheduled oil changes. While driving, the vehicle suddenly began producing a significant amount of smoke and the check-engine light came on. After I pulled over, fluid was visibly leaking from underneath the vehicle. A State Trooper responded and told me I was lucky the vehicle did not catch fire. The vehicle was disabled and had to be towed from the highway to the VW dealership. The VW technician subsequently diagnosed the oil separator as having failed. In a video inspection provided to me, the technician stated that the failed oil separator caused excessive pressure in the engine crankcase, which "blew out" the upper timing cover and oil pan. The dealership replaced the oil separator, upper timing cover, and oil pan. The dealership then performed an approximately 30-mile test drive. The technician stated that the oil level remained full, but the vehicle produced a "big blue plume of smoke." He then stated, "there's an issue with these vehicles and the cylinder heads," and advised that the cylinder head now needs to be replaced. The vehicle remains at the VW dealership. I am reporting this because the failure occurred suddenly at highway speed and resulted in substantial smoke and fluid loss, creating a potential fire and safety hazard. I am also concerned that significant blue smoke continued after the initial repairs and that the vehicle now requires major engine repair at fewer than 28,000 miles. Thankfully, there were no injuries or collision. uploaded: text with svc advisor, stating part of this is a known issue; screenshot from the video the dealer sent me - the web address to view the video is at the top. i do not have the police report yet
